rl`his invention relates to improvements in dirigibly mounted lights.

One object of the invention is to provide a universally adjustable light involving mechanism of simple, durable and substantial construction and so arranged that the vldjustment may be effected easily, the arrangement being especially adapted for spotlights to be employed on automobiles.

Another object of the `invention is to provide, in .a dirigibly mounted light, a control switch or switches for the electric circuit of a noved and efficient character and which may be actuated by the same hand of the operator used in effecting the adjustments of the light and without shifting of the position of the hand.

vOther objects of the invention are to pro-4 vide `an adjustably mounted spotlight having the parts thereof so designed that they may be economically manufactured and assembled and the parts applied to a vehicle with' a minimum 'of el'ort and instruction.

In the drawings forming a part of this specification, Figure 1 is a vertical sectional view taken through the corner post of a closed type of automobile superstructure and showing my improvements in connection therewith. Figure 2 is a horizontal, sectional view, upon a larger scale, correspending to the line 2-2 of Figure 1. Figure 3 is an enlarged side elevation-al view of the inner end of the mechanism adjacent the steering wheel. Figure 4 is a sectional View corresponding to the section'line 4:-4 of Figure 1, but upon a larger scale. Figure 5 is a view similar to Figure 1 but upon a larger scale, illustrating certain of the parts at the inner end of the mechanism,

and more particularly certain electrical connections and switch. And Figures 6, 7 and 8 are sectional yviews corresponding to the lilies 6--6. 7-7 and 8-8, respectively, of Figure 1 but upon a larger scale.

In said drawings, 20 indicates a corner post of the superstructure of a closed type of automobile or other part of the superstructure such as a windshield or the like and to which my improved light is adapted to be attached. In lthe instance shown, the spotlight is primarily designed for use on closed types of cars and is readily accessible for operation from the interior at a point.

convenient to the driver and in proximity to the usual steering wheel.

vIn carrying out my invention, I employ a bracket 21 adapted to be secured to the corner post 2O by screws or other lsuitable fastening devices. Said bracket 21 is provided with lan outstanding hub or bearing sleeve 22 and with an inwardly extending elongated bearing sleeve 23 passing through a' corresponding opening made in the end post 20. Preferably, I also .employ a sup- `plemental bracket 24 on` the inside of' the post 20 andsecured thereto, said bracket 24 having a short supporting hub 25, as shown in Figure 1.

Rotatably mounted with respect to the supporting bracket 21 and on an axis extending approximately horizontally, is what may be termed generically a housing or hollow head A, the latter as shown, having a hollow cylindrical arm or shaft 26 comprised ot' a short integral section and a tube rigidly secured thereto. Said arm 26 extends laterally from the'head A and within the bearing provideditherefor by the sleeve portions 22 and 23 of the bracket 21, said arm 26 being egrtended inwardly beyond the end of the sleeve 23, as best shown in Figures 1 and 5. With this arrangement, it is evident that the member A is adapted to rotate ,about .a horizontal axis to thereby effect adjustment of the light in one plane.

The housing A has also an integrally formed cylindrical flange '27 'extending4 from one side thereof and at right angles to the hollow arm 26. Said flange 27 .provides a shouldered bearing for a lamp-carrying member 28 to which is secured a casing 29. A

The casing 29 is provided on the interior thereof with a refiecting mirror 30, an electric lamp bulb 31, and the usual lens 32. The base of the electric bulb is slidably mounted within a suitable casing 33, the base having a flange 34 between which and the mirror is an expansion springj35. Pivoted to and Within the casing or shell y 29 is a lever 36 having a projection 37 bearing upon the inner end of the base of the bulb, said lever being adjustable from the exterior of the shell 29 by a knurled adjusting screw 3,8. IVth this arrangement it is evident that the focus of the electric bulb can be adjusted without dismantling any of the parts and also that the lamp-carrying member is rotatable on theousing A about an 'axis at right angles to theaxis of rotation of the housing A, thereby )roviding for the universal adjustment'of t eli* light, ,as-,will be obvious.

Rigidly secured to the inner extended endy of thehollow arm 26 as by a pin 39is a preferably cast block or handle support 40, Said block 40 having a hollowAV semi-cylindrical box, the arcuate walls." of which are i'ndicated at 41 and the flat wallat 42. Said box is adapted to be closed by a suitable'V cover plate 43 secured in place byscrews 44 or other suitable fastening devices Mounted in said semi.cylin lrical` box is a transversely extending shaft 45 having suitable bearings in thebottomwvall and cover plate of the box and extended both above and below. Said shaft 45 is rotatable about an axis perpendicular to the axis of the rotatable hollow arm' 26,'as clear from an inspectionA of'Figure l.

. The upper end ofthe shaft 45as viewed in Figure 4, is of reduced cross section as l indicated at 45, the lower extended end 45 'latter cooperatingwith a bevelgea-r 49 rigidly` secured tov the inner end of a hollow l shaftwhich extends through and is ro` tatable within the'hollow arm or shaft 26. 'Y The op osite end of saidhollow shaft 50 has rigid ly secured thereto and extending within the housing A, a-bevel Year 51 which Ameshes with abevel1'gear 52 ormed on the top of and `preferably'integral with a pinion or gear 53 rotatably mounted on a stud 54. The gear or pinion 53, in turn, meshes with a second gear or pinion 55 integral or rigid with the adjacent end of the lamp-holding. member 28. With this arrangement, it is evident that oscillation of the hand lever 46 about the axis provided by the shaft 45,

will produce a corres ondmg rotation of the lamp-holding inem er 28 about its axis on the housing A. l

Furthermore, swingingof the hand lever- 46`bodily ina plane perpendicular to the axis ofthe hollow arm26 willv produce ro-.l

tation of ksaid hollow arm 26-and housing A about. the axis Lof' rotationfof` the latter,

V`thus: obtaining the` 1 universal adjustmentsl of ythenla-in'p proper {themanipulation of withthe pin 63,v carries a tweenv limitingpinsmf; 4

a single element. It will be further'observed that the two separate adjustmentsl referred to may be obtained in sequence or simultaneously and combined.

To preventrotation of the lamp-holding member "28a-bout its particular taxis accidentally, as from jarrino` or vibration, the

lower member 46b of the lever handle is provided with a hub 46 with which frictionally vcooperates a split friction band 56 lcarried byav block` 57 which is secured to.

the under side'ofl the block 40, as best illustrated in Figulo'4.

To prevent Iaccidental rotation of the housing A about its particular axis, as a.result of vibration or jarring, the block 40 is provided with a split sleeve extension 58 which frictionally cooperates with a lead-in block 59, the latter rigidly' secured to sleeve 23, as' by the pin 60. To supply the electric current to the bulb 31, I preferably u`se the grounded syste-m and the following wiring and switch controls, the current being supplied from any suitable source of, power on the vehicle, as

the bearing vfor instance the storage battery. The positive side of the circuit is brought from the battery by a wire insulated within thecable 61, the latter being secured in position by a friction clamping band 62, to the fixed bearing sleeve 23 and preferably adjacent the bracket member 24. The end of said wire 61 is led within `the lead-in block 59 and there connected to an'insuiated pin 63 extended parallel to thev sle fe 23. -Slidably mounted back and fortli parallel to the sleeve 23 within the lead-in'b'lo'clk -59 is ablo'clr of insulation 64 which, on the side in alinement contactl element 65 vcoopera le with the exieldably 'female tended end ofthe pin 63 in all positions'of y the insulated blockv 64. vThe female contact member 65 is in turn electrically connected with an annular contact ring .66 mounted in the block of the insulation64 with which is adapted to co-operate a spring-pressed coni tact pinl 67 mounted'in an insulated bushing 68p carried by the block 40. The pin 67 is in turn electrically connected with a spring linger 69extending `within the semicylin rical box L11`43 and opposite to a contact pin 7() n'iountekl in allginsulaterl bushing carried vby theadjacent end of the hollow sha-ft 50. The spring finger 69' normally tends to niove away from and out of.

contact with-the pin 70 but is adapted to be y forced into e'lectrical' Contact with: the other Aby means of "a cani-block ofy insulating Ina.- terial 71 secured to the bottoinend yof ashaft 72, rotatablyv mounted in a-stiitablebearing provided on the coverv plate I l43,- `the upper end ofrsaidishaft 72'having`an operating finger or'. le'if'eff. '.Tliejla'tf through ani are Qf'ffaipproxi second lamp-holding Figure 3. By 'swinging the finger 73, it is evident that the spring finger 69 can be moved into or allowed to move out of contact with the contact finger 70. The block of insulation G4 is adapted to be shifted in order to break the circuit-between the ring 66 and pin 67 by a finger piece 75 rigid with the block G4: and extending outwardly through a slot 76 in the block 59. In this manner I provide two control switches, either of whirh may be employed as found most convenient by the operator and depending upon the position of his hand at the time he d esires to make or break the circuit.

From the pin is extended a wire 77 connected to a Contact pin 78 mounted in a bushing of insulation rat the inner end of the hollow shaft 50. Coperable with the contact pin 78 is a spring finger 79 insulated from the housing A and electrically connected with a second spring finger 80 which bears upon the upper end of a contact pin 81 mounted in a bushing of insulation carried by the lamp-holding member 28. From the pin 81 is extended a wire leading'to the positive contact point at the base of the Vbulb 31. Vith this .arrangement it is evident that the electrical circuit may be maintained with the bulb regardless of the position to which the light is adjusted. It will also be noted that theelectric wiring is Weather protected throughout and there arel no wires which may be twisted, regardless of the operation which takes place.
